Are products uncoated with bare metal of the pin section defective?

Latest Updated:01/01/2008

Question:

I received your products uncoated with bare metal of the pin section close to the package body. Are they defective?

Answer:

Depending on the package, some products may be processed like this, so it is not a defect.
For discrete and linear IC products housed in a through-hole type package (products that are dipped rather than coated), as long as the pins are covered as far as the stopper section (the boundary between the thin and thick parts), the product is OK.
Also, in some 3-pin minimold packages (SC-59) that have a slightly broad area near the base of the lead, this area may not be coated. The 2SA812A is one such example (the 2SA812, however, is fully coated).
